Definitions
- a method for manufacturing a GRIN lens according to the present invention is characterized by including a step of forming a wet gel from an alcohol solution containing, as main components, a silicon alkoxide, a dopant alkoxide, and an aluminum alkoxide, a step of dissolving by leaching the dopant and aluminum away from the outer peripheral surface of the wet gel to provide a refractive index distribution, a step of forming a dry gel by drying the wet gel, a step of forming a glass preform by firing the dry gel, and a step of wire-drawing the preform.
